Diddy, 49, was with Porter on-and-off from 1994 until they split for good in 2007.

They had three children – Christian, 20, and twin daughters Jessie James and D’Lila Star, 11 – together.

The record producer and entrepreneur has three more children from other relationships and Porter had a son – Quincy Brown – from her previous relationship with singer Al B Sure.

Brown, 27, was largely raised with Diddy, is an actor and appears on the Fox musical drama Star.

As an actress, Porter appeared in the 2011 film Mama I Want To Sing and on the TV series Wicked Wicked Games in 2006 and 2007.

In 2002, during one of their break-ups, Porter took Diddy to court over child support but the couple later reunited and had their twins four years later.

However, they broke up again – six months after the girls were born – with Porter saying it was her decision at the time.

She said in a statement: “In ending this relationship, I made a decision that was in the best interest of myself, Sean and our family.

“I look forward to moving on with my life and my career, and wish him prosperity, health and happiness in life and in love. We will remain friends and committed parents to our children.”

In one of her final Instagram posts earlier this month, she shared a photo of Diddy, wishing him a happy birthday and thanking him for “giving me the best gifts of life, our CHILDREN!”
